Product Description

Silicone Ruber Composite Insulator

Polymer line post insulators are applied to high voltage power line service. Polymer post insulator is consisting of ECR fiber-glass core rod or porcelain core rod, composite housing and compositesheds with injection mode outside of core. Silicone rubber post insulator have characteristic of un-puncture same as ceramic post insulator, the composite shed is provide high resistance of pollution. Line post composite insulator was got more and more extensive use.

Composite polymer post insulator have features of good gydrophobicity, anti-ageing, anti-leakage trace and electric erode proof,tensile strength and bending strength, silicone rubber post insulator have strong mechnical strength,shock resistance good quakeproof and brittle failure proof,light weight and silicone rubber post insulator is easy to installation, and the installation size of top and base are the same size with porcelain type, they can exchange to each other.
